That's an excellent description of the MEL
, maybe the best I've ever seen. I have to wonder if it is from the preamble in your company's document?? In any case, I hope you don't mind if I use it! I'm building a training program and I need a nice description.
A cracked, shattered or delaminated cockpit window is a pretty regular ocurrence, but there are many causes, which can include a failure in the anti-icing grid, a crack in a pane, a bird strike, or a delamination caused by a separation of the window layers.
I once heard that the windshield on the B757 is the toughest ever made, because when it was tested, the testers fired frozen turkeys at it, and had to beef it up some more to pass. In reality, the frozen part was unnecessary, as it's rare to run into a frozen bird at 15,000 ft! I don't know if this is true, but it makes a good story!
